An Alabama corrections officer was among the 15 suspects arrested as part of a child sex exploitation sting in Montgomery.

Montgomery County law enforcement officials on Monday announced the arrests stemming from an undercover sting targeting child exploitation.

On Tuesday, a Department of Corrections spokeswoman confirmed that one of the suspects — 43-year-old Flanzy Lee Harris — was an officer at Kilby Correctional Facility in Montgomery.

Harris resigned from his position following his arrest, said ADOC spokeswoman Kelly Betts.

Montgomery County Sheriff Derrick Cunningham called the suspects’ conduct “something serious” during a Monday press conference. “This is something we’re not standing for and it’s something we addressed.”

The massive sting took several months of training and planning.

Assistant Chief Deputy Wesley Richerson of the Montgomery County Sheriff’s Office said they were targeting people who prey on children. Those arrested, he said, communicated online with who they believed to be children and agreed to pay them for sex acts.

Montgomery police Chief Darryl Albert called the suspects “the worst kind of predators’’ and District Attorney Daryl Bailey said, “the children of Montgomery are a little safer today.”

To parents, Richerson said, “Please review and monitor what your children are doing online and who they are taking to. You would not leave your front door wide open – your child’s phone, if unmonitored, is an open door to their life.”

“This operation surpassed all expectations,’’ said Chief Deputy U.S. Marshal Dante Gordon.

The other suspects besides Harris charged with first-degree human trafficking, electronic solicitation of a child and traveling to meet a child for an unlawful sex act were:
